The Federal Opposition says the Government's industrial advertising campaign is full of spin and propaganda and does not include details of how worker entitlements like penalty rates are under threat.

Treasurer Peter Costello said that the changes will lead to a stronger economy, which in turn will create more jobs and higher wages.

But Labor's industrial relations spokesman, Stephen Smith, says while the government advertisements say conditions like penalty rates will be protected by law, the fine-print indicates they can be 'sold down the river'.

"It's the removal of the 'no disadvantage test' which enables public holidays, leave loadings, rest breaks, meal breaks, penalty for overtime and shift allowances to be removed without fair or adequate or any compensation - these are the things that can be removed at the stroke of a pen," he said.

The Opposition says low income earners will struggle more if the Government gets its way.

Mr Smith says the minimum wage would have been reduced if it was not for the Industrial Relations Commission.

"If the Government had had its way before the Industrial Relations Commission, the minimum wage would currently be 50 dollars a week or 2,600 dollars a year worse off," he said.

"The minimum wage would have been reduced in real terms by 1.5 per cent over the Government's term rather than having increased by 12 per cent."

You have no doubt been hearing a lot about the Paris Agreement and know that it pertains to climate change, but are too embarrassed at this stage to ask for an overall explanation of what it's all about.
